Units explained
Square Dekameter
A square dekameter is a metric unit of area equal to 100 m². It is identical in value to the are.
Derived by squaring the dekameter (10 m). The deca- prefix comes from the Greek 'deka' (ten).
Square dekameters are functionally equivalent to ares. In contexts where the prefix system is preferred, dam² may be used in place of 'are' for clarity.
Dekameter has been part of the metric system since 1795.
Square Zeptometer
A square zeptometer is a metric unit of area equal to 10⁻⁴² m². It is one of the smallest defined SI prefix area units and is primarily theoretical.
Derived by squaring the zeptometer (10⁻²¹ m). The zepto- prefix was adopted by the CGPM in 1991 from the Latin 'septem' (seven), denoting the 10⁷ thousand-grouping.
Square zeptometers appear only in theoretical particle physics literature when comparing cross-sections at extreme scales. Not used in any measurement context.
SI prefix zepto- adopted in 1991; remains a defined but practically unused unit.
Square Dekameter to Square Zeptometer conversion formula
The relationship between square dekameters and square zeptometers:

Step-by-step: convert square dekameters to square zeptometers
- Write down the value in square dekameters (dam²).
- Multiply that value by the factor 1e+44.
- The product is the equivalent value in square zeptometers (zm²).
- To reverse, multiply the square zeptometer value by 1e-44.
Worked examples
Example 1 — Convert 1 dam² to zm²:
1 × 1e+44 = 1e+44 zm²
Example 2 — Convert 100 dam² to zm²:
100 × 1e+44 = 1e+46 zm²
